Starting with the 1 Pf. in 1960, followed by the 10 Pf. in 1963, and the 5 Pf. in 1968, the old style coins were gradually replaced with new coins depicting the state name "Deutsche Demokratische Republik." Aluminium 1 Mark, 2 Mark and 50 Pfennig pieces were released for circulation in 1956, 1957 and 1958, respectively. In 1969, brass 20 Pfennig coins were introduced, with nickel-bronze (later cupro-nickel) 5 Mark coins issued from 1968. In 1973 and 1974, 1 and 2 Mark coins were redesigned dropping the former "Deutsche Mark" title. The brass 20 Pfennig coins were issued partly because pay telephones had a standard charge of 20 Pf. and were having problems with smaller aluminium coins jamming due to their light weight. Commemorative 5, 10, and 20 Mark coins of various types have also occasionally made it into circulation.
In 1995, an elite military school invited a notorious neo-Nazi, who had spent years in prison for his role in a bombing, to give a talk. In 1997, video footage emerged of soldiers making anti-Semitic comments and imitating the Nazi salute. In 2003, a former general of the German special forces, Reinhard Günzel, congratulated a German conservative member of parliament on revisionist statements comparing Jews to Nazis. Günzel was subsequently fired; in 2006 he published a book, called Secret Warriors , lionizing the Nazi-era roots of German special forces.
